It features an M5x0.80 thread and a 25mm length under head, with a low-profile button head that suits flush or near-flush mounting requirements. The screw is manufactured from Grade 12.9 alloy steel with a black oxide finish, giving it a hardness of 38 HRC. Installation requires a 3mm hex socket driver. This fastener meets ANSI\/ASME B18.3 and ASTM F835 standards, making it suitable for precision and structural fastening work performed by machinists, millwrights, and maintenance technicians.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in applications where a low-profile head is required and tensile strength is critical. The Grade 12.9 rating places it among the highest-strength metric fastener grades, appropriate for hydraulic components, machine tool assemblies, jig and fixture construction, and equipment frames. The right-hand thread and metric sizing make it compatible with standard metric tapped holes in industrial and OEM manufacturing environments. Thread fit classes 4G and 6G provide options for both close-tolerance and general-purpose fits.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 12.9 alloy steel construction with 38 HRC hardness for high-load fastening\u003c\/li\u003e\n  \u003cli\u003eLow-profile button head with 9.5mm head diameter and 2.75mm head height\u003c\/li\u003e\n  \u003cli\u003e3mm hex socket drive for positive torque transfer\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for mild corrosion resistance and reduced light reflection\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI\/ASME B18.3 and ASTM F835 standards\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread, fully threaded, metric M5x0.80 specification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit metric fastener for M5x0.80 threaded holes in machine assemblies, fixtures, and equipment requiring a button head profile.
